COMBINED IMPLEMENT FOR DE'lACHlNG AND REPLACING THE PARTS OF SMALL-ARMS.

Specification forming part of Letters Patent No. 4.7,7l5, dated Ma-y 16,1365; antedated May 1, 1865.

1'0 all whom, itmay concern:

Be it known that I, ALEXANDER GRILLET, of Philadelphia, Pennsylvania,have invented an Improved Gun Appendage; and I do hereby declare thefollowing to be a full, clear, and exact description of the same,reference being had to the accompanying drawings, and to the letters ofreference marked thereon.

My improved gun appendage consists of a compact instrument (fullydescribed hereinafter) to be carried by a soldier and to be used by himfor the purpose of operating on his fire-arm, the instrument being suchthat it can be used for withdrawing and replacing the mainspring, can beadjusted for use as a screwdriver, as a band or tumbler punch, a wrenchfor withdrawing and replacing the nipple, and as a medium for carryingthe wiper and ballscrew.

In order to enable others skilled in the art to make and use myinvention, I will now proceed todescribe its construction and operation.

On reference to the accompanying drawings, which form a part of thisspecification, Figure 1 is a plan view of my gun appendage; Fig. 2, anedge view; Fig. 3, a plan view the reverse of that shown in Fig. l, andFig. 4the same as Fig. 3 with the arms or plates open.

Similar letters refer to similar parts throughout the several views.

The instrument consists of two main plates or arms, A and B, which arehinged together at w, and which can be made toassume the two positionsseen in Figs. 1 and 4.

On the outer end of the arm A is a projection, a, in which is a squareopening adapted to the square portion of the cone or nipple, so thatwhen the latter has to be screwed to or unscrewed from the gun the arm Aacts as a wrench, of which thearm B forms the handle,

'the two arms being in the position shown in Fig. 4. A stud, b, issecured to and arranged to turn on the outer surface of the arm A, andfrom this stud project two pins, the long pin 6 consisting of a plaincylindrical rod of steel, and serving as a tumbler-punch, and theshorter pin having screw-threads adapted to similar threads in anopening in the neck of the wiper H, the ball-screw L being also screwedinto the neck of the wiper.

The end or of the arm B serves as a large screw-driver, and when used assuch the arm A, occupying the position seen in Fig. 4, forms the handle.

To a pin projecting from the outer face of the arm B are hinged thesmall screw-driver c and band-punch d, which together form, at

' the point where they are connected to the arm,

a hub or stud, 3, alluded to hereinafter.

It will be seen that two pins or studs, 1 and 4, project fronnthe outerface of the arm B, and that a stud, 2, projects from the arm A. Theobject of these studs and the duty they have to perform will be bestobserved on reference to Figs. 3 and 4, in which the main spring of thegun is shown in red lines.

When the mainspring has to be withdrawn from the lock, it is in thefirst instance com pressed by operating the hammer, so as to assume theform seen in Fig. 3. Theinstrument is then so applied to the lock thatthe studs 1, 2, 3, and 4 shall occupy the position in rela tion to thespring seen in the said Fig. 3. The hammer of the lock is then released,so that the spring may be distended and bear against and be controlledby the above-mentioned studs, when on moving the instrument away fromthe lock it will carry with it the mainspring, which can be readilydetached from the instrument after the two arms have been moved to theposition shown in Fig. 4, and the spring thereby permitted to becomedistended.

It will be understood withoutexplanation how the instrument can bemanipulatedfor the purpose of restoringthe mainspringtothelock.

WVhen the two arms are folded together, as seen in Fig. 3, they arelocked to each other, a pin, f, on one arm entering aholein the other.This lock is so light, however, and the arms are so thin that by wedgingthe end of the thumb between the arms near the end of the same one armcan be easily unlocked from the other.

When a ball has to be withdrawn from the barrel of a fire-arm, theball-screw L is un-' screwed from the neck of the wiper H and attachedto the ramrod, and when the wiper has to be used it can be readilyunscrewed from the pin which projects from the stud b and attached tothe ramrod.

When the instrument is not required for use,

the several parts occupy the relative position illustrated in Figs. 1,2, and 3, and are con; tained in so small a space that the instrumentcan be carried in the pocket without incon- Venience.

The manner in which the instrument has to be adjusted to operate on thescrews, band, nipple and tumbler of the fire-arm will be readilyunderstood without further explanation.

- I claim as myinvention and desire to secure by Letters Patent- 1. Thetwo arms A and B, hinged to each other and provided with the studsherein described, or the equivalents to the same, the whole beingarranged for acting on the mainspring of afirearimsubstantially asdescribed.
